Muaj ntau cov khoom lag luam subdivided ntawm cov iav siab borosilicate iav. Vim tias qhov sib txawv ntawm cov txheej txheem ntau lawm thiab kev nyuaj siab ntawm cov khoom lag luam siab, tus lej ntawm cov lag luam sib txawv hauv kev lag luam sib txawv, thiab lawv cov lag luam kev xav tau txawv.
High borosilicate iav, tseem muaj lub iav nyuaj, yog lub iav ua los ntawm cov khoom siv ntau lawm los ntawm kev siv hluav taws xob siab ntawm cov iav kom ua tiav lub khob. High borosilicate iav muaj qhov tsis tshua muaj cua sov nthuav tawm coefficiention. Qhov linear thermal expansion coefficient ntawm "Borosilicate iav 3.3" yog (3.3 ± 0.1) × 10-6 / k. Lub borosilicate cov ntsiab lus ntawm lub iav muaj pes tsawg leeg yog qhov tseem ceeb. Nws yog Boron: 12.5% -13.5%, silicon: 78% -80%, yog li nws yog hu ua High borosilicate iav.
High borosilicate iav muaj cov hluav taws tsis kam zoo thiab lub zog siab. Piv nrog cov iav uas nquag muaj, nws tsis muaj tshuaj lom thiab cov kev mob tshwm sim. Nws cov yam ntxwv xws li, siv tshuaj stability, tshuaj pauv hloov, cov dej tsis kam, alkali kuj, thiab acid tsis zoo yog qhov zoo dua. siab. Yog li ntawd, siab borosilicate iav tuaj yeem siv tau dav hauv ntau lub teb, cov tub rog, tsev kho mob, tshuab ntxhua khaub ncaws, siv lub tshuab ntxhua khaub ncaws, microwave cub tais diav, hnub ci Dej tso cua sov thiab lwm yam khoom.
Nrog kev txhim kho nrawm ntawm Tuam Tshoj cov qauv siv thiab nce kev nthuav dav ntawm cov khoom siv high borosilicate ntawm cov khoom siv high borproof, optics thiab Lwm thaj teb, tsav Tuam Tshoj lub siab borosilicate iav lub iav lag luam thov tau qhia kev loj hlob sai ntawm kev loj hlob sai. Raws li "kev soj ntsuam kev lag luam thiab yav tom ntej kev txhim kho cov kev tshawb fawb ntawm Tuam Tshoj hauv Suav teb yuav yog 409,400 tons nyob rau hauv 2020, ib xyoos -Yog li cas txog 20%. 6%.
Muaj ntau cov khoom lag luam subdivided ntawm cov iav siab borosilicate iav. Vim tias qhov sib txawv ntawm cov txheej txheem ntau lawm thiab kev nyuaj siab ntawm cov khoom lag luam siab, tus lej ntawm cov lag luam sib txawv hauv kev lag luam sib txawv, thiab lawv cov lag luam kev xav tau txawv. Muaj ntau cov lag luam ntau lawm nyob rau hauv lub tshav pob ntawm qis-xaus thiab high-kawg borosilicate iav, xws li cov khoom siv tes ua thiab khoom siv hauv chav ua noj. Muaj txawm tias qee hom kev ua haujlwm sib txawv ntawm kev lag luam, thiab kev ua lag luam kev xav tau tsawg.
Hauv teb ntawm high borosilicate iav cov khoom siv nyob rau hauv lub hnub ci zog, tshuaj lom neeg, muaj ntau cov tuam txhab ua lag luam yog cov kev xav tau yog qhov siab. Kev noj lub siab high borosilicate iav-resistant iav ua ib qho piv txwv, muaj ntau cov tuam txhab hauv tsev uas tuaj yeem tsim cov hluav taws kub siab-resistant iav.
Tseem muaj ntau chav rau kev txhim kho hauv daim ntawv thov ntawm high borosilicate iav, thiab nws txoj kev loj hlob loj hlob los ntawm doda dog dig silica iav. Technologist los ntawm thoob plaws lub ntiaj teb tau them ntau rau siab borosilicate iav. Nrog rau kev siv nce zuj zus thiab xav tau rau iav, siab borosilicate iav yuav ua lub luag haujlwm tseem ceeb hauv kev lag luam iav. Nyob rau hauv lub neej yav tom ntej, siab borosilicate iav yuav tsim muaj nyob rau hauv cov kev coj ntawm ntau qhov kev qhia tshwj xeeb, muaj ntau qhov zoo, thiab loj-teev.
